This invention relates to illuminating attachments for temperature observing devices,

and is particularly suited for use in connccyinometer devices are either of a character necessitating that they be built into the device during the process of original manufac ture or such asflto, constitute anextr'aneous attachment objectionable both from considera- 1 Wtions Tof appearance and utility. Inasmuch of devices ofthisfcharaoter now in use which 1 are notf'provided with any means forthe'ilas there are said to be-hundreds of thousands lumination: thereof" whenneeded, the owners of such devices a're'fde'si'rous of obtaininfpg atc i ts' h ref suc as "wi e l them Tito: enjoy theladvantages of an illuminatedfde vice during night driving without either necessity of. discarding their present devices or of applying thereto. an attachment which will l f ,render' same offensively objectionable V in api .to provide an attachmentof the characterde f scribed which cai'idbev applied totem?

-It is ani" portant ob ofthis invention rvingldevicfes already in use.

expensive manufacture. gfwhich will not'im- "p air the appearance qf he thermometer def -.vice to; whi h it is applied; which: is simple and durable; which, caiibe quickly applied I f an ordinary mechanic without the use of any special tools, orv "appliances and without cutting, bending or otherwise re-forming any} part of the, thermometer device and which is" not so formed as to partlcularly invite lodgment thereon of dust,"mud, snow or ice, espef cially in such manner as tojimpalr the effec;

tiveness thereof.

Still furtherobjects will be in part obvious and inpart more specifically stated in the description of this invention. hereinafter set forth.

With the aforesaidobjects in view, this in-- vention consists of. the novel features of device of Fig. 1.-

H. bjectQQiS-Ito provid such an: at tachnient whjchl issuited for rapid and in structure and arrangement of parts pointed out in the subgomed claims and heremafter described with relation to a specific embodi- "ment thereof illustrated inflthe annexed drawing, wherein like parts are designated by similar reference characters, and in which Figure 1 is a side elevation, partly in section; of an attachment embodying this invention together with a thermometer device for. use with which said attachment is suited,- and 4 Fig. 2 is a face view of theattachment and In order to facilitate comprehension f of I this invention, and for 'convenience of illust-ration an embodiment thereofis' shownby the accompanying drawing in connection with a'well-known form'offtemperature observing device comprising the annular frame 21, the pedestal 22 upon which said frame is mounted, the thermometer tube-23 contained within saidfr'ame and pedestal, the dial plate 24 mounted within saidframe atone; side of said thermometer the bezel 25 carrying the crystal 26 and secured to aside of theframe 21 (at the otherlside of said thermometer) by screws 27, the bezel -'25"carryingthe crystal 26 which, in the absence of the attachment of th s invention, is secured to the other side of sald frame by screws similar to the screws 27, and thesuppleme'ntal dial plate 24, which is; undenlike conditions, clamped between the bezel 25 and'th-e dial plate 24; 1 yj The temperatureohservin'g device thus far descrihedis shown as'havin'g an illuminating attachment associated therewith, which attachment 'is-illustrative of this invention. and comprises the annular member and *the receptacle 32 for the lamp 33.

Said member 31 has a peripheralcontour harmonizing with those of the'frame 2i and the bezel 25, and the opposite faces of said member are so formedas to be suited for interposition betweensaidframe and bezel, to make snug jointstherewith. Said member is so formed as to provide forpassagethere through of the attaching screwsQT .which serve to holdboth this attachment and said bezel in'intended relationship with the frame 21; the central opening through said member being of such size 'and'forrn as to provide space for mounting therein the receptacle 32. and lamp 33, and so as to provide for the passage of light from said lamp let 1 through suitable openings in the dial plate 24 to the tube of the thermometer 23.

deemed preferable to provide a slot 28 in the .dial plate 24 extending downwardly from It is the opening 29 regularly provided in such plate, said slot being so positioned as to proride for the illumination of the tube of the thermometer 23 for a suitable distance below 7 the conventionally indicated conductor 35,

the opening 29. It is also believed to be desirable to provide covering of translucent material, as indicated at 30, for the slot 28 and opening 29, so as to prevent direct glare from the lamp 33 from reaching the eyes of the driver of a vehicle upon which the device and attachment shown have been mounted; it may also bedesira-ble that the covering of the opening 29 shall be of a color distinctivefrom that of the covering of the slot 28.

The terminal 3a communicates with they receptacle 32, and said terminal passes through the side wall of the member 31 and projects from the periphery thereof so as to facilitate the supply of energy to the lamp 33 from a conductor, such, for example, as

which conductor may be provided with a spring contact such as that indicated at 36 for readily detachable connection with said terminal 34;. i V In order to prevent escape of glaring rays 1 from the lamp 33 through'the opening 29 provided in the supplemental dial plate 2%, a translucent screen 37 is so applied as to cover said opening; said screen being of such a character as will permit sufficient light to enter through the opening 29=during the day time (when the lamp 33 is notburning) as will suitably assist the observer in ascertaining the position of the indicating fluid in the tube of the thermometer 23.

In applying the attachment oi this inwen tion to adevice such as that shownpthe screws which originally held the bezel 25 in PIZICQJQI'Q first'removed, this bezel taken of and the supplemental dial plate '24 also re-v moved; then if sameis not already therein provided, the slot 28 may becut in the dial plate 24 and, if it is desired to use such shields, the covering 30 may be applied to the dial plate 24 and the translucent screen 37 correspondingly applied to the supplemental dial plate 24:. A suitable lamp 33 should then be placed in the receptacle 32, and the member 31 should be placed in in-, tended relation with the frame 21 so that the openings provided for the attaching screws through said member will register with the threaded openings provided in said frame.

The supplemental dial plate 24: and the bezel 25 should then be applied to the outer face of the member 31, and secured in position by the screws 27. 5 c

It will be understood by those skilled in this art that the member 31 may be of such other than by thescrews 2 diameter that the screws 27 may pass through the principal opening through said. member or outside of the periphery thereof, in either of which events it would be unnecessary to provide openings through said member for such screws; it will also be readily understood that the member 31 and bezel 25 may be secured to the frame 21 7 as shown; and that yariousother modifications of structure and arrangement may bemade without departingfrom the spirit of this invention.

What 1 therefore claim and desire to secure by Letters Patent of the United States of America is: v p I 1. An attachment fora temperature observing device having a frame of annular comiguration with threaded openings there in for receiving attaching screws of a cover for one side of said frame, 'and tjhe 'cover having openings positioned for registry with the threaded openings in' said framesaid attachment comprising an annular member suited for interposition between the frame and cover'ofsuch a device, said member having openings therethrough" so positioned that, whensaid member is interposed between the frame and cover of such .a deyice, said openings theret'hrough will reg ster with and form channels oflcommunication between the threaded .openlngs in such frame and the corresponding openings in. said :cover, andareceptacIe for lighting means supported and contained within said member.

2. An attachment fora temperature observing device having a franie'of annular configuration with threaded openings therein for receiving attaching screws of a cover for one side of said frame, and the cover having openings positioned for registry with the threaded openings insaid fram'e,said attachment comprising an annular member suited for interpositronbetween the frame vframe,said attachment comprising a memher so formed that, when interposed in the intended manner between the frame and cover of such a device, passageway-will be provided for cover attaching screws, and a receptacle for lighting means supported and contained within said member.

4. An attachment for a temperature observing device having a frame of annular configuration, a cover adapted to close one side of said frame, and meansfor attaching said cover to said frame,said attachment comprising an annular member suited for interposition between the frame and cover of such a device, and lighting means'supported and containedwithin said member between said frame and said cover.

5. An attachment for a temperature observing device having a casing with a removable wall section,said attachment comprising an extension member for said casing,

said member having an opening therethrough for a suitable lamp and having a peripheral contour harmonizing with those of such casing and its removable wall section and being formed and arranged for interpositioning therebetween to thereby separate said movable wall section a sufiicient distance from said casing to provide space for such a'lamp, a receptacle within said opening positioned for therein supporting such a lamp, and a terminal for the supply of energy to member having an opening therethrough for a suitable lamp and having a peripheral contours harmonizing with those of such casing and its removable Wall and being formed and arranged for interpositioning therebetween to thereby separate said movable wall section a sufficient distance from said casing to provide space for such a lamp, and a receptacle within said opening positioned for therein supporting such a lamp.

In witness whereof, I hereunto subscribe my name, this 3rd day of January, 1924.
